Supernatural, Arrow, Flash, Supergirl stars together at PopFest

At EW PopFest in Los Angeles on Saturday, Supernatural stars Jensen Ackles and Jared Padalecki joined forces with the stars of The CW’s four superhero shows, Arrow‘s Stephen Amell, The Flash‘s Grant Gustin, Supergirl‘s Melissa Benoist, and DC’s Legends of Tomorrow‘s Caity Lotz for one mind-blowing, super-duper photo posted on most of their respective Instagram accounts.

“This is the crossover we need,” Amell wrote, winning the caption contest among the six stars.

“Thanks #ewpopfest for a fun afternoon!” said Ackles. “And apparently a #cwtv cast get-together! Good times.”

Gustin posted an image of the gang in action, noting, “Here’s a shot of @jaredpadalecki smacking my ass and me not hating it.”
